【 摘 要 】

Oil contaminated sites are the consequence of a long period of industrialization. Oil is a complex mixture including aliphatic and aromatic hydrocarbons, which are known to have negative effects on human health and the environment. Dividing oil products in groups (fractions) of petroleum hydrocarbons that act alike in soil and water, one can better know what happens to them. Being able to understand the behaviour of oil products in soil, it will allow to implement prevention and remediation actions. Interventions on contaminated sites are bound to comply with regulatory limits that each country has set in their own environmental legislation. The different concentration thresholds of oil products in soil for several EU countries and Canada has led to compare: limit values, analytical method, soil characteristics and/or land use. This will allow to evaluate what could be the best regulation approach, assessing if it is better to consider soil matrix in the site or the specific land use or both of them. It will also assess what is the best analytical methodology to be adopted to achieve the pollutant concentrations in the soil in order to have comparable results among different countries, such as: Baltic countries (Latvia, Estonia, Lithuania), Nordic countries (Finland, Sweden, Norway, Denmark), Western countries (Italy and The Netherlands) and Canada, like gaschromatography in the range from C10-C50. The study presents an overview of environmental regulatory system of several EU countries and Canada and the correlation between different parameters about oil products indicated in each environmental legislation.
